Authorities from the Brookhaven Town fire marshal’s office and Suffolk County police arson squad continued Monday to try to determine the origin and cause of last week’s blaze that raced through a section of Fire Island Pines, destroying four homes and damaging two others.

The Friday fire on the barrier island was reported shortly before 1 a.m. at a home on Ocean Walk, Brookhaven Chief Fire Marshal Chris Mehrman said in an interview on the day of the blaze. He said the fire was fueled by winds of up to 30 mph that caused it to quickly spread to two homes on Pine Walk and one on Cedar Walk.
